We use Mattermost to coordinate attendance at 'dugnad', our weekly meetings. The way we do it is having a bot posting announcements that we react to with a ✅ if we're attending.
With many members, some people, especially newer members might stop attending without giving a notice of it. Though we of course don't like this situation, we need to keep our member list up to date as an adminstrative matter. Querying the Mattermost API is a method to check for this situation, and is the goal of this project.
- Install Rust and Cargo, for example using https://rustup.rs
- Run
cargo runin this repo - Enter your Mattermost username at the prompt
- Enter your Mattermost password
A table will be printed. This contains the username of each user, the last date where they reacted with ✅ to a message from friBot in the dugnad channel, and the total number of ✅ reactions they've made to such messages. In the situation where the user is deleted, it will show 'unknown user [their id]'.
Pay attention to the Mattermost API Reference.
This program uses the mattermost_api crate. This crate has very few built-in functions, and more or less requires you to formulate your requests manually.
This formulation has been done by consulting the api, and generating some structs for deserializing responses using this website: https://transform.tools/json-to-rust-serde.
This did not turn out perfectly for a couple of reasons, so the structs defined in src/apitypes.rs are not exact matches of what the API will return.
Take note that our chat server URL, friBot's user id, and the dugnad channels' channel id are hardcoded.
